DISPENSING APPARATUS.

SPEClFIGATON forming part of Letters Patent No. 676,130, dated J' une 11, 1901. Application led August 16, 1900. Serial No. 27,010. (No model.)

To @ZZ whom, t may concern.:

Be it known that I, CHARLES S. GooDEEL- LOW, a citizen of the United States, residing at Lowell, county of Middlesex, State of Massachusetts, have invented an Improvement in Dispensing Apparatus, of which the following description, in connection with the accompanying drawings, is a specilication, like characters on the drawings representing like parts. e

This invention relates to a dispensing appara-tus, and though capable of containing and delivering many different substances it is of peculiar importance as a receptacle for ice-cream and materialof a similar nature which is affected by warmth.

The apparatus represented in one convenient embodiment thereof is simple in construction and serves to maintain ice-cream, butter, or the like in a solid condition and to regulate with exactness the quantity to be supplied to a purchaser.

Figure 1 isa side elevation of a dispensing apparatus constructed in accordance with my invention in a simple form. Fig. 2 isla Vertical central sectional view of the Sallie. Fig. 3 is a sectional plan view of the discharge or delivery end of the appliance, showing part of the feeding mechanism and the actuating mechanism therefor and areceptacle in dot ted lines; and Fig. 4 is a sectional detail of a projection adapted to be operated by an actuator.

The apparatus in the embodiment thereof illustrated includes in its construction two containers, a main one and an auxiliary one, in communication with each other, and these may be of any suitable character.

The main container is denoted by A, and it may consist of a cylindrical metal can inwardly tapered at its lower end, as at 12, the tapered portion merging into the reduced neck 13, adapted to rest upon the bottom of the tapered portion 14: of the receptacle B. The receptacle B is shown as polygonal in cross-section, and it may be made from sheet metal or any other suitable or desired material. The receptacle B is shown having a series of legs, as 10, secured to the base or platform 11, adapted to rest upon a counter or other support.

The main container A is supported centrally, or substantially so, within the receptacle B and is separated therefrom by the metallicV jacketing 15. In the spacepbetween the jacket 15 and the receptacle B is a filling of heat-insulating material, as 16, and this ordinarily consists of ground cork, cork being well adapted for the purpose, and 1 prefer to pack around the main container A crushed or broken ice, as 17, or any other refrigerant. 4The jacket 15 is shown united with the receptacle B bythe {iange or web 1S.

The main container receives the removable casing or cylinder 19, which can be taken therefrom and supplied with cream, butter, or the like, and it is covered with the anged cap 20. The case or cylinder 19 is open at both'ends, and after being supplied -with cream lfrom a freezer said ends are covered to retain the cream therein; but Just before the case is inserted in the container both e covers are taken od, so that the cream can be forced from the case into an auxiliary container, as will hereinafter appear. Access of air to the cracked ice 17 is prevented by the ring 21, fitted between the cap 2O and the jacketpl at the upper side of the apparatus.

The cream from the case 19 is forced thereit expels a quantity of the contents of thel container A therefrom. Any suitable mechanism may be employed for actuating the feeddevice.k The stem 23 is shown as hav-v ing a rack 24' upon one side thereof, adapted to be engaged by thepinion 24 at the inner end of the shaft 25, supported by suitable bearings upon the detachable top 26.' The shaft 25 carries loosely at its outer end the worm-gear 27, meshing with the Worm or screw 28 upon the upright shaft 29, supported upon the outside of the receptacle B. The upright shaft 29 carries a beveled gear 30 at its lower end, meshing with a similar gear 31 on the horizontal shaft 32, carrying a handle, shown as a crank 33. The normal and shifted positions of the handle 33 are shown by full IOO neously advance one and to retract the other.

The first one always moves in the same direction, but the other one is reciprocatory, and hence toprevent the first one from being operated upon the return stroke of the second onevl provide mechanism of a peculiar nature Which will maintain the primary or main feed device in its advanced position during the return ofthe auxiliary feed device. This mechanism may be of any suitable character.v That `shown I will now describe. The shaft carries-at its extreme outer end the ratchet 34, fixed thereto, and the sprin g-actuated pawl 35coperates therewith, the latter being pivoted to the ,outer face of the Worm-gear 27 and `both of them being located in the recess'or c 0ncavity36 in said outer face. lThe substance is forced from the main container A into an auxiliary container, as C, shown as forming a rigid prolongation of the receptacle B and as being substantially in the form of a cylindrical trough open at its upper side and communicating with the main container through the throat or discharge-orice 37 and extending rearward from said receptacle.

The auxiliary container C incloses an aux-` iliary feed device, shown as a cylindrical plunger 38. The action is such that this plunger-38 is retracted or drawn back when the inain plunger 22 is moved down, so that a vsupply' of cream can be delivered to the empty auxiliary container. Upon the forward movement of the auxiliary plunger 38 it serves to force the substance within the auxiliary container therefrom into a suitable vessel, the discharge-outlet of the auxiliary container being controlled -by a suitable valve or gate,

as 40'. The auxiliary plunger 38 is retracted or drawn back by gearing, and itis illustrated as having upon its upper side a rack 4l, meshing with the pinion 42 upon the rock-shaft 32. When the lever 33 is swung down in the manner previously specified, the plunger 22 will be forced down and the plunger 38 will be drawn back in unison therewith, which permits the first-mentioned plunger to eject a charge of cream from the container A into the communicating container C. When the lever is drawn back, the plunger 38 will be moved forward, whereby the cream in the container C is forced therefrom. During the forward movement, however, of the plunger 38 the plunger 22 does not operate, it being retained in its advanced position.

The valve 40, controlling the delivery-outlet of the auxiliary container, is fixed to the rock-shaft 45, supported by brackets, as 46 and 47, upon the apparatus, and is held normally closed by suitable means, as the coiled torsional spring 48, embracing said vshaft and 'This projection 49 coperates with the actuator D, shown as a longitudinal bar having a right-angular head 54, secured to theV extreme outer end of the auxiliary plunger 38. Said actuator or bar also has an offset intermediate its ends in which the projection 49 is normally disposed, as shown in Fig. 3, whereby the valve is held closed. The free end of the actuator or bar has a downwardlydeflected portion, as 56, adapted to 'coact with the projection 49. As the plunger 38 is drawn back the actuator D of course moves therewith, and just after. the commencement of the stroke the upper end of the projection 49 will be engaged by the forward end of the actuator, the said projection being moved l down for a slight distance and being still farther moved when it is encounteredby the downward deflection 56. Uponv the return movement of the plunger, however, the actuator operative therewith will be guided under the projection 49 by the deflected por-I `permit the discharge of the cream contained `within the auxiliary container.

Vhen the offset 5,5 is reached, the projection 49 will be released and will pass out of contact with the actuator, whereby the valve 40 will be freed and instantly closed by the coiled spring 48. v

Not only the valve 40 but the feed device or plunger 38 serves to exclude Warm air from the interior of the apparatus, and the contents of the latter are thereby kept in a desirable and solid condition.

IOO

The apparatus previously described is simple in construction, and by regulating the stroke of the hand-lever 33 the quantity of substance to be supplied from the apparatus can be governed. v

The invention is not limited to the exact construction previously specified, for this may be varied within the scope of the accompanying claims.
